The Waring House (also known as the "Waring-Stockslager Home") is a historic house in Greenville, Ohio, United States. Built by Oliver C. Perry, the house was started in 1860, but construction was only substantially completed in 1869, and the details took two more years to finish. As soon as he had finished the house, Perry sold it to T.M. Taylor, who in turn sold it to the family of local businessman and county commissioner Thomas Waring. Waring and his family were the first individuals to occupy the house, taking up residence in November 1874. The Waring House is a brick structure that rests upon a foundation of stone; it is topped with a roof of asphalt, and various other elements are made of metal. Its overall floor plan is rectangular, although modified by the addition of three wings to the rear. The dining room is a major part of a substantial two-story, two-bay wing attached to the main portion of the house, while two single-story wings — a single-bay structure in the form of a large pavilion, and a double-bay structure containing the kitchen — are in turn attached to the dining room wing. Among the Waring House's leading architectural elements are its windows, especially the distinctive segmental windows of the dining room wing. Overall, the house is a fine example of the Victorian style of residential architecture; although many nineteenth-century Greenville houses have been well preserved to the present time, few are as pristine as the home of Thomas Waring. In recognition of its historically significant architecture, the Waring House was listed on the National Register of Historic Places on September 16, 1977; it was recognized as important primarily in the local community. Six other Greenville houses — known as the Beir, Coppess, Garst, Lansdowne, Leftwich, and Robeson Houses — have been accorded a similar honor; the Waring House was the fourth of these seven buildings to receive this designation. Today, the Waring House is operated as a bed and breakfast.

The Donovan Robeson House is a historic house in Greenville, Ohio, United States. Located along Fourth Street west of downtown, the Robeson House has been ranked as the city's most significant Queen Anne mansion.

The Benjamin Franklin Coppess House, built in 1882, is a historic Queen Anne and Stick-Eastlake style house located at 209 Washington Street in Greenville, Ohio, United States. This historic residence is made more beautiful by the extraordinary flower gardens planted expertly by the current resident- accenting the property and period structures (gazebo/pavilion) within. Definitely worth driving by in May 2021.

The Leftwich House is a historic house in Greenville, Ohio, United States. Built in 1875, the house features a combination of the Italianate and Stick-Eastlake styles. A frame structure built upon a foundation of stone, it was one of the most well-preserved Stick-Eastlake houses in Greenville and the surrounding area, with a porch that has been described as "outstanding" and a gable that is ornamented by specifically Stick elements. Unfortunately, as of May 2021, the house has fallen into disrepair, with shutters hanging askew or missing, the exposed wood is noticeably rotting and exterior paint peeling and bubbled all over. The house's floor plan is unusual; its four-bay western facade is divided between two components of two bays each; through the northern component, one may enter the house through a Victorian front door. An Eastlake porch shelters the rear door that opens onto the protruding kitchen, and various eaves elsewhere on the exterior form separate cornices, each of which is composed of brackets and a frieze. Covering the house is a hip roof, which consists primarily of shingles. In 1975, the Leftwich House was listed on the National Register of Historic Places because of its excellent architecture. Although the house's history included no distinctive events or residents, its architecture was rare enough to qualify it for listing.

The Anna Beir House, built in 1865 by Conrad Beir, is a historic two-story redbrick house located at 214 East 4th Street in Greenville, Ohio. Miss Anna Beir was a longtime art teacher in Greenville, who devised the house to the city of Greenville upon her death in the 1930s. It was used by the Greenville Art Guild for many years until a fire in the 1970s. A gallery in the Greenville Carnegie Library is named for Miss Beir. On April 11, 1977, the house was added to the National Register of Historic Places. When he built the house, Conrad Beir was simultaneously serving as the pastor of the German Methodist Church in Greenville and in business as a tailor. His daughter Anna was born in the house in 1873, and it remained her residence until her death in 1939. The house is a plain brick structure built in a simple rectangular shape, two stories tall; the gabled facade is divided into three bays. Set on a stone foundation, the brick house is topped with a metal roof and features miscellaneous stone elements; it is typical of middle-class residences of the period. For much of her life, Beir was a prominent educator; her thirty-six-year tenure in the city schools gave her a high reputation both locally and in the wider region. Although multiple colleges attempted to win her away, her dedication to Greenville and her influence on the city's residents prompted her to decline all such requests in favor of remaining with her native city.

The Broadway Bridge is a historic arch bridge that spans Greenville Creek on the edge of downtown Greenville, a city in the far western part of the U.S. state of Ohio. Constructed in the early twentieth century, it carries one of the city's most important streets and connects the city's northern and southern sections. One of several large concrete bridges designed by a Cleveland engineer, it has been named a historic site.

The Lansdowne House is a historic house in Greenville, Ohio, United States. Built in 1870, it was the residence of Zachary Lansdowne, who was a pioneer in the development of the U.S. Navy's airship program and commanded the airship Shenandoah. A native of Greenville, Lansdowne attended the United States Naval Academy upon graduating from Greenville High School; as Shenandoah's skipper, he was killed in its crash on September 3, 1925. Architecturally, the Lansdowne House is unremarkable. It is a simple two-story rectangular frame structure, topped with a shingled roof and supported by a foundation of limestone. In 1979, the Lansdowne House was listed on the National Register of Historic Places. It qualified to be added to the Register because of its connection to Zachary Lansdowne.

The Treaty of Greenville, also known to Americans as the Treaty with the Wyandots, etc., but formally titled A treaty of peace between the United States of America, and the tribes of Indians called the Wyandots, Delawares, Shawanees, Ottawas, Chippewas, Pattawatimas, Miamis, Eel Rivers, Weas, Kickapoos, Piankeshaws, and Kaskaskias was a 1795 treaty between the United States and indigenous nations of the Northwest Territory (now Midwestern United States), including the Wyandot and Delaware peoples, that redefined the boundary between indigenous peoples' lands and territory for European American community settlement. It was signed at Fort Greenville, now Greenville, Ohio, on August 3, 1795, following the Native American loss at the Battle of Fallen Timbers a year earlier. It ended the Northwest Indian War in the Ohio Country, limited Indian country to northwestern Ohio, and began the practice of annual payments following the land concessions. The parties to the treaty were a coalition of Native American tribes known as the Western Confederacy, and the United States government represented by General Anthony Wayne and local frontiersmen. The treaty became synonymous with the end of the frontier in that part of the Northwest Territory that would become the new state of Ohio.
